Yes animals are so giving, without expecting anything back. Humans could take a page from the animal world.
I will be honest, I am not really a pet person, growing up we always had a dog, but I never really had much to do with them. Move ahead 30 years and my daughter who I live with bought a yorkie terrier, I think thats the name of the breed. Anyway shes been here for 2 years, and I cant imagine life without her. Her and I lay around the same way, watching tv, eating. I love her, and that surprises me, and makes me feel good.
Take care, hope all are having good days
